ADOLPH MAEULEN, OF WILLIAMSPORT, PENNSYLVANIA, ASSIGNOR TO WILLIAMS-PORT MIRROR & GLASS COMPANY, OF WILLLAMSPORT, PENNSYLVANIA.

WINDOW-VENTILATOR.

Specification of Letters Patent.

Patented June 1G, 1914.

To all whom it may concern Be it known that I, ADoLPH-MAEULEN, a citizenof the United States, residing: at Williamsport, in the county ofLycoming and. State of Pennsylvania, have invented new and usefulImprovements in Window-Venti- J lators, of which the following isalspecificax tion.

The invention particularly relates to window ventilators employing atransparent front plate and collapsible. segmental side members ofextremely light and strong construction.

In connection with the accompanying drawing, forming a part of thisspecieation j and wherein like numerals of reference designatecorresponding parts throughout the several views: Figure 1 is a view inside ele- -vation of the side or end members of the ventilator with thefront plate'and window v structure in vertical sect-ion.' Fig. 2 is a.ver-

tical sectional view Ithrough .the side .or .endf

member; Fig. 3 is a transverse sectionali v1ew taken through Fig. 2 onthe line 3 3. Fig. 4 is a View in side elevation of aportion of amodified form of side .or end member with the front plate in verticalsection. Fig. 5 is a side elevat-ion of a rear portion of Fi 4. Fig. 6is atop plan view of a modie form of side or end member. Fig. 7 is aview in elevation of a portion of the form of Fig. 6, and Fig. 8 is avertical sectional view taken through Fig. 1 on the line 8 8.

Reference numeral 1 designates the window frame, 2 the window sill, and3, the window sash, to which the invention is applied. The inventionconsists broadly of a front glass plate 4 and two sides or end members.In the drawing onl one side or end member is illustrated, but 1t will beunderstood that there is aside or end member attached to each end of thefront plate 4V and toeach side of the window frame. Each side or endmember consists of two segmental plate sections 5 and 6. The side plate5 is bent inwardly at right angles entirely along its front edge forminga fiange 7 behind which the glass front plate 4 is placed. The frontplate 4 is engaged along 4its opposite or rear side by a flange 8 of aseparate L-shaped bar, the other flange 9 of said bar bearing flat uponthe side plate 5. The flange 8 is adjustable toward the flange 7 bymeans of bolts 10 to securely clamp the front plate 4. The upper edge ofthe plate 5 is vcnt out as at 12 thereby providing spaced :lugs or stops14-1-5, one adjacent each side .edge of the plate 5. 'The side plate 6comprises f-ront and rear spaced walls 16 and 17,

lintegrally connected along their side edges as at 18, by bending onefrom the other. The upper end portion 19 of the wall 17 is bent overupon the wall 16 closing the upper end of the plate 6 against entry ofrain water. A portion 20 of the wall 17, which extends as at 21 beyondthe side edge of the wall 16 throughout, is bent around the side edge ofthe wall 16 embracing between itself and said wall 16 the bent overportion 19 of the Wall 17 the former openings 22 permitting i-nsertionof a screw driver to drive screws 22 into the apertures 22 to secure`the plate 6 to the side 1 of the window frame. The plate 5 is inserted'between the walls 16 and 17 of the plate 6, the stop 2O .being receivedin the cut-out portion 12 and ,engageable' with stops 14 and 15. Bothplates 5 and 6 at their lower ends have registering openings to receivepivot screw 25 which passes into the` window sash. Vhen secured togetherin this manner, 'the plate 5 is freely movable between the walls 16 and17 of plate 6, the-stop 15 engaging stop 20 preventing entire withdrawalof plate 5 In the modified forms, the plates vfand 6 are the same as inFig. 1, except ,vv/ith respect to the receiving portion for/the frontplate 4. In Figs. 4 and 5 the/,L-bar 26 is similar to the bar 8-9 ofFig. 1 though turned around. This bar has beaded fastenings '27 whichenter openings 28 and slide into diagonal slots 29 in the plate 5 tocrowd the bar against the glass front plate 4. In Figs. 6 and 7, theside portion of plate 5 is bent to provide inwardly extending doublewall flange 30 and single flange 31, connected by portion 32 alined withthe body portion of theplate 5. Between these par-` allel flanges 30 and31, the glass front pla'te is inserted.

What/is claimed as now is 1. In a window ventilator, a segmentalside/plate having means for connection with a r,front member, a secondsegmental side plate having double walls and slidably receiving betweenits walls the first plate, a

stop extending across the space between the 116 Y Walls of the secondplate, the first plate haning a cut out portion receiving said stop andthe end Walls of the cut-out portion being engageable with the stop toarrest movements of the irst plate in the second plate, and said platesbeing pivoted together.

2. In a Window ventilator, a segmental side plate having means forconnection with a front member, a second segmental side plate bent uponitself and slidably receiving between its Walls the first plate, oneWall of the second plate extending beyond the other Walland the sameWall having a portion bent around the' said other Wall forming a stop,the first plate having a cut-out portion receiving said stop; ,M Y

3. In a Window ventilator, a segmental side plate having 'means forconnection With a front member and also having a cut-out portion, asecond segmental side plate bent upon itself forming double Walls, theupper edge f one Wall being bent upon the other Wall, a portion of theside edge of one Wall being bent upon the other Wall forming a stop,said plates being pivoted together with the stop received Within thesaid cut-out portion. Y

4. In a vvindoitT ventilator, a segmental side plate having means forconnection with a front member, stops extending beyond said upper edge,a second segmental sido plate of double Wall formation, the Walls beingconnected along their side edges, the upper edge of one Wall being bentaround the other Wall, a portion of the side edge of one Wall being bentaround the other Wall and constituting a stop, the side'edge of one ofsaid walls extending beyond the other and beyond the last-mentionedstop, the first side plate being slidably received between the Walls ofthe second side plate, the stop of the second side plate being receivedbetween the stops of the first side plate, and the said plates betingpivoted together adjacent their lower en s.

5. In a Window ventilator, a side plate having a right angular flangealong one edge, an L-shaped member having one of its flanges parallelWith and movable with relation to said right angular flange, and theother flange of the L-'shaped member bearing flat upon the said sideplate.

In testimony whereof I have hereunto set my hand in presence of t-Wosubscribing witnesses.
